7. The system of claim 6, wherein the end portion of the inner conducting rod of the first connecting arm extends longitudinally past said end portion of said outer conducting body of the first connecting arm.

8. The system of claim 4, wherein said first conducting element of the first hub is electrically connected to said second conducting element of the first hub by means of at least one conducting plate disposed within the first hub.

9. The system of claim 8, wherein the first hub includes an electrically conductive outside body, and said conducting element of said first arm mount is electrically connected to the conducting element of said second arm mount by means of said outside body.

10. The system of claim 9, wherein said at least one conducting plate is electrically separated from said outside body by means of an insulating element.

11. The system of claim 1, wherein the first connecting arm has a circular cross-sectional shape, or a polygonal cross-sectional shape.

12. The system of claim 1, wherein the inner conducting rod of the first connecting arm has a circular cross-section, and the outer conducting body of the first connecting arm is annular.

13. A ceiling lighting system comprising:

a canopy disposed along the ceiling and a power source;
